1 / 21 page 1 ® ADS7818 ADS7818 ADS7818 DESCRIPTION The ADS7818 is a 12-bit sampling analog-to-digital converter (A/D) complete with sample/hold, internal 2.5V reference, and synchronous serial interface. Typi- cal power dissipation is 11mW at a 500kHz through- put rate. The device can be placed into a power down mode which reduces dissipation to just 2.5mW. The input range is zero to two times the reference voltage, and the internal reference can be overdriven by an external voltage. Low power, small size, and high-speed make the ADS7818 ideal for battery operated systems such as wireless communication devices, portable multi-chan- nel data loggers, and spectrum analyzers. The serial interface also provides low-cost isolation for remote data acquisition. The ADS7818 is available in a plas- tic mini-DIP-8 or an MSOP-8 package and is guaran- teed over the –40 °C to +85°C temperature range. 12-Bit High Speed Low Power Sampling ANALOG-TO-DIGITAL CONVERTER ® FEATURES q 500kHz THROUGHPUT RATE q 2.5V INTERNAL REFERENCE q LOW POWER: 11mW q SINGLE SUPPLY +5V OPERATION q DIFFERENTIAL INPUT q SERIAL INTERFACE q GUARANTEED NO MISSING CODES q MINI-DIP-8 AND MSOP-8 q UNIPOLAR INPUT RANGE International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
